I’d like to be able to recommend stuff to other users I’m associated with, like to my son. It’s hard to remember every good movie I’ve seen, but when I remember them, I’d like to come to plex and add it to a list for him to see. Also allow him to see what I rated the movie, so he can see them ranked.
Checkout the option to manage recommendations in your server settings. This allows to publish a collection to friends… which could be a classic collection to which you add the movies you’d like him to see, or a smart collection based on some label/tag you ca apply to those movies.
